Example 8: How many different way can be formed by using all the letters of the words “FEBRUARY” so that the vowels always come together ?Answer: The word contains 8 different letters. In this word vowel letter present “EUA”, we consider it as one letter.
So, letter be arrange as FBRRY (EUA).
We can arrange 5 letters as 6P6 = 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720 ways.
we can arrange vowel as 3! = 3 x 2 x 1 = 6 ways.
So required number of words = (720 x 6) = 4320.

Example 9: How many different way can be formed by using all the letters of the words “COMPUTER” so that the vowels always come together ?Answer: The word contains 8 different letters. In this word vowel letter present “OUE”, we consider it as one letter.
So, letter be arrenge as CMPTR (OUE).
We can arrenge 6 letters as 6P6 = 6! = 6 x 5 x 4 x 3 x 2 x 1 = 720 ways.
we can arrenge vowel as 3! = 3 x 2 x 1 = 6 ways.
So required number of words = (720 x 6) = 4320 ways.
